Importance: Congenital Zika syndrome virus infection is said to interfere in children's development. Objective: evaluate gross motor trajectories and the frequency of cerebral palsy in children with congenital Zika syndrome. Design: Cohort study applying the Alberta Infant Motor Scale (AIMS) and the Bayley III Scales in infants from 6 to 18 months of age. Setting: The SARAH network, Rio de Janeiro. Participants: Thirty-nine infants whose diagnoses were established through clinical history, serology tests, and neuroimaging findings. Main outcomes and measures: Congenital Zika syndrome is associated with severe motor delays and is a risk factor to the diagnosis of cerebral palsy. Results: The Alberta Infant Motor Scale mean raw score at 6 months was 9.74 (SD 4.80) or equivalent to 2 to 3 months of motor developmental age. At the age of 12 months, 14.13 (SD 11.90), corresponding to 3 to 4 months of motor development age; the Bayley III Scales results correlated to the Alberta Infant Motor Scale (P < .001) at this age. At 18 months, 15.77 (SD 13.80) or a motor development equivalent to 4 to 5 months of age. Thirty-five of 39 children (89.7%) met criteria for the diagnosis of cerebral palsy. Conclusions and relevance: Gross motor development marginally progresses from 6 to 18 months of age. These individuals also displayed a high frequency of cerebral palsy.

Objective: To perform a systematic literature review to analyze existing data on the neurological effects of coronavirus on newborns. Data sources: We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P), and searched the PubMed and Embase platforms for the keywords [brain damage OR pregnancy OR developmental outcomes] and [coronavirus OR SARS-CoV-2 OR SARS-CoV OR MERS-CoV] between January 1, 2000 and June 1, 2020. Data synthesis: Twenty-three reports described the course of pregnant women exposed to SARS-CoV-2, SARS-CoV, or MERS-CoV during the gestational period, eight to SARS-CoV-2, eight to SARS-CoV, and seven to MERS-CoV. No data were found on abnormalities in brain development or on a direct link between the virus and neurological abnormalities in the human embryo, fetus, or children. Spontaneous miscarriage, stillbirth, and termination of pregnancy were some complications connected with SARS/MERS-CoV infection. SARS-CoV-2 is not currently associated with complications in the gestational period. Conclusions: The literature has no data associating exposure to coronavirus during pregnancy with brain malformations and neurodevelopmental disorders. However, despite the lack of reports, monitoring the development of children exposed to SARS-CoV-2 is essential given the risk of complications in pregnant women and the potential neuroinvasive and neurotropic properties found in previous strains.

Background Early child development is a critical stage of life that influences social, educational and health outcomes worldwide. A few years after Zika epidemic, families of children born with congenital Zika syndrome (CZS) continue to face uncertainties when it comes to the development of their children. The present study sought to analyse the developmental trajectories of a subset of children born with CZS in the first 24 months of life. Methods Thirty‐five children with CZS were assessed with the Bayley‐III Scales at 12 and 24 months of age from November 2016 to December 2018 in a rehabilitation centre in Brazil. Inclusion criteria included children with established diagnosis of CZS. Exclusion criteria included the presence of arthrogryposis, prematurity, irregular follow‐up, clinical complications or other causes of microcephaly. Children born with CZS who evolved with cerebral palsy (CP) were classified according to the Gross Motor Function Classification System (GMFCS) at 2 years of age. Results At 12 months of age mean composite scores on the Bayley cognitive, communication and motor scores were 57.71 (SD 7.11), 57.94 (SD 14.34) and 49.26 (7.20), respectively. At 24 months of age, composite scores were 57.43 (SD 7.11), 53.60 (SD 12.29) and 48.83 (7.76). In addition, 31 (88.57%) out of 34 children diagnosed with CP were classified as GMFCS levels IV and V. Conclusion Zika virus congenital infection is a risk factor for functional impairments across all developmental domains having a direct and substantial negative impact in early child development.

Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.
